specification of Letters Patent. Patented' NOV, 13, 1917,

Application filed October 8, 1914. Serial No. 865,767.

the following` is a specification.

This invention'relates to improvements in 1 collapsible beds ot the character Vbroadly claimed in Letters Patent of the vUnited States, No. 1,101,481, granted to me June 23, 1914, and comprel'iends a combination oi' bed frame elements, pivotal connecting elements for the frame elements, a bed spring frame relatively movable to collapse into a limited space and rigidly spaced bedk post sections carried by the mattress frame and interlocking with thepcollapsing bed post sections in the extended positionrto form a rigid bedrstead of neat, original and ornamental appearance, that can be readily and conveniently collapsed into compact form for storage and transportation without detaching any of the parts. l

rlhe' invention also comprisesV various novel features, elements and combinations as will more Jfully appear from the drawings herewith and the subjoined detail description.

1t is an object of the invention to so relate the frame elements, the cornorvposts, the interlocking mechanism, and the connecting braces, that the bedstead shall be more attractive in appearance when the bed is open, that the bedstead shall hold the bedding and mattress securely when the bedstead is in the collapsed position, and that the collapsed bedstead may be stored in minimized space.

A further object of the invention is to provide a bedstead, capable in the collapsed position of being moved through a doorway of the ordinary height and width and that may in thel collapsed position be concealed in a recess in the Wall. y f

A. further object of the invention is to so provide for counterbalancing the weight of the bed springs and bedding, that the attendant may told the bed to collapsed position with greater ease.

.A further' obiect of the invention isto provide a compensating adjustment to bal ance the bed springs withA variablefweight of mattress and bedding,

A. further object of theinvention is to minimize weight in a vcollapsible bed.VK This is accomplishedby making the connecting y braces and the bed spring trame serve as the collapsing mechanism, and arranging the pivotal eonnections to shift `in position as thebed is folded, so thatthe line of direction` of the kmattress frame, mattress and bedding is through the pivotal axis of said trame, and said trame will stand vertically edgewise when the bed is collapsed,

A still' further objectis'toprovideim-V proved means to hold tliev bedstead securely in open position.

,y While the elements shown and' described i are. well adaptedV to serve the purposesfor which they are intended, it is to be understood that the invention is not limited to the precise construction exhibited herein, but may include variations and modifications which may fall within the scope of the appended claims, the essence of the invenrelatively movable to a. collapsed position, and a tilting spring fi ame coperating with the bedstead sections to change and secure the bed in either open or collapsed position, the combination and arrangement of the elements being ornamental rather than machine-like in appearance. Y y

Other objects and advantages may appear from' the subjoined detail description and the adaptation of the invention shown in the drawings. f

Q0. 21 xed to non-rising posts 3, 7, 11and pivotal connection with brackets 22, post members 4. 8. l2, are provided, the four setsof tongs insuring proper alinement of the posts in the collapsing movement. The lazy tongsconnections 15 are;horizontal,.that'isto say, theirpivots `being,determined iby rollers 32,

`from, their llocking locking .each bolt limits-the movement of the sliding bolts. IThe opposite side of trames 2i .in :brackets 19.

a are vertical, and the lazy tongs 18 are vertical, that isto say, their pivots I) are horizontal. yBy the arrangement shown each side frame is connected to the center frame having the vertical posts 3 by the lazy tongs '2 and which as 15 are horizontal with vcrtical pivots, and the other two, 18, are ver- ,.ticalivithhorizontal pivots b. By this arrangement and construction perfect alinement and parallelism between the trames -ivhile Lthef bedstead is expanded and also )vhile itis-collapsed are maintained.

A mattress or bedspring frame Q-l, consistingof endbars 25, preferablyfoiangle giron, side bars l2G, vholding theend bars in opposed relation, and Adepending brackets 27,v Q8,` connecting` the `.side lbars with.` the end Lbars, is pivotallymounted at its middle relativeitoithe central -bed frame section 1. the

`endbars 25 being provided -with hangers Q9 ,swinging upon pivotal pins 30 fixed to Abrackets 220D .slidingsection 4 of posts 3. The central posts 3 are provided With-trunn ion brackets 20 carrving trunnions 31 on which aremounted rollers 32, the rollers 32 beingadapted to engage `with curved cams 33 formed as guide ways in parts integral ivitli hangers 29. The bed spring frame may thereforelbe tilted on `its longitudinal axis to a vertical position; its path of movement following rtheguide Ways 33.

ocking means for securing `the spring frame 24-in open position arc provided com- ,prisingslidingbolts l-fmonnted in brackets .28. the bolts 3.4 passingtbrouah holes35 providedin brackets19. Brackets 19iixed to corner posts 7, have angularly disposed strike Vtacos 36, .which automatically actnate the :bolts aslthe frame 211 is turned to the open position.' To Withdraw the sliding bolts positions` they are provided .with rods 37. connected at one end to Vthe slidingboltsand at thefother end to a tumbler 38,.'thetumbler 38 being fixed to a rotating rod39 provided with an operating handle 40.

A spiral spring` Ll1 havingl one end fixed to rod 39 and its opposite end fixed tosidebar 26, serves to actuate the rod and tumbler to throw sliding bolts 3l into the position, and a `fixed collar Ll2 on is supported in the open positionbv brackets 27 dropping into engagement with brackets lwhich are xed to corner posts 11of thetbed lframe.

Brackets '27, 28, have dovetail tenons 43. 44 which slip into corresponding sockets 45 21 when the bed spring frame approaches the horizontal position.

Additional lmeans lfor locking the bedstead in open position comprise trames or kend locking .sections `46. having supple- -mentary `posts47, and `tubular cross bars 48,

49, hold posts 47 in opposed relation. These frames constitute post-engaging means pivotally mounted on the mattress frame to hold the mattress frame in horizontal pothe closed position of the bed. These frames constitute post-engaging means which as shown in Fig. llmay form a rigid joint to vhaving pivotal connection prevent collapsing as will more fully appear in the following description.

f A latch in the form of a tapered plunger in each supplementary post is adapted to engage with a corresponding socket 51 fixed in each of post sections 8, 12. lEach plunger 50 is held in engagement with a socket 51 by a spring 52 interposed between a collar 53 fixed to the plunger, and a bushing 54 fixed within the post 47.Y Each plunger 50 has a hollow7 piston 55 having a slot 56 in the wall thereof having teeth 57 extending in the slot and forming a rack. A rotating rod 58 having pinions 59 engaging with racks 57 extends through eachfof the cross bars 48, and the rod and pinions are adapted to operate the pistons and plungers simultaneously in their respective supplementary frames. To disengage plunger 50 a knurled rotating handle 60 is provided in the top of each of posts 47, said handle 60 being secured against end movement by a pin 61 'projecting from the walls of the post into an annular groove 62 of said rotating handle 60. Miter gears 63 transmit motion from handle 60 to rods 58, and thus by turning handle 60 the plungers may be withdrawn against the tension of springs 52.

Each of the plungers 50 is provided with a. trigger 64, pivotally secured to collar 53, the trigger being actuated by a spring 65 to engage with a detent 66, secured to the wall of post 47. The plungers 50 may therefore be withdrawn from their corresponding sockets 51, thereby releasing supplementary posts 47 and permitting frames 46 to be folded upon the bed spring frame 24. Each of posts 47 is provided with a bracket 67 with a bracket 67 secured to frame 24, the brackets 67 being shaped to allow the frames 46 to fold upon and secure the mattress and bedding (not shown) in the closed p'os'ition'of the bed. f

Means for releasing plungers 50 consist of releasing rods 68, one of which is slidably mounted in and co-axial with each plunger, and projects from the end thereof, the inner end of the releasing rod bearing against the trigger 64. Sockets 51 have slots 69 through which ends 70 ofthe releasing rods pass as the frames 46 are folded upon frame 24; each slot having a rocker 71 actuated by a spring 71 and swinging outward as the frame begins -its folding movement.Y The rockers are rounded at their upper ends and actuate the releasing rods 68 which in turn actuate triggers 64 and there- 'byrelease plungers 50 as the frames approach the open position.

A rigid link 7 2 pivotally secured to a lug 73 on bracket 16 and pivo-ted to a lug 74 on hanger bracket 29 coperates with the cam wayv 33 and roller 82 to collapse the bed frame as the spring frame 24 is tilted; the

link 72 causing the -aXis of frame 24 to rise as the mattress or bed-spring frame approaches the edgewise vertical position. Means for adgusting the tension ofsprings Y75' consist of vplungers 76 each having a vflattened vtoothed upperV end 77 and rotating members 78 fixed against end move- Ament by pins 79Vaiid mounted in the upper ends of members 4, the members 78 Abeing-threaded to engage with ends 77 of plungers 76. Ends 77 slide through corresponding` slots 80 in pins 80. By turning members 78 the tension of springs 7 5 may be adjusted in accordance with the weight of the moving parts of the bed.

To counterbalance the weight of the bed spring frame and whatever weight of inattress and bedding may be carried thereon, posts 8 have interior coiled springs 75 which actuate plungers 76, connected with the telescoping members 4. rThe springs may be adjusted so Ythat the spring frame will. slowly rise automatically to the vertical position when bolts '34 are released from lool?- 'ing engagement with brackets 19.

Assuming the bed to be in the open position as shown in Figs. 1, 2 the method of changing to the collapsible position may be understood from the following description. First, the knurled handles 60 are rotated until the plungers 50 are released. End frames 46 are then swung over into parallelism with the mattress frame as indicatedby dotted lines in Figs. 2 and 11 to a position approximately parallel with spring frames 24. Second, the handle 49 is turned thereby releasing locking bolts 54 whereupon frame 24 under action of the lifting springs 75 will be slowly turned from horizontal'to vertical position. The tilting of frame 24 will cause members 4, 8 and l2 to move upward relative to posts 3, 7 and 11 respectively, thus spreading and thereby shortening the four sets of lazy tongs which consequently draw the outer bed frame sections toward the central section all of which is effected simultaneously with the tilting movement of frame 24. The lazy tongs operating in both vertical and horizontal planes preserve the alinement of the bed frame sections iii the collapsing movement and collapsed position of the bed. i

To open the bed the edge of `the mattress frame will be grasped by the attendant andy brought to horizontalposition, the operative parts above described operating in a manner obvious from the foregoing, and ivhenthe mattress frame reaches the locked horizontal position the locking eiidiscctions Will be moved up into locking position shoivn in Figs. l, 2 and l1.

In the open position of the bed, the frames 46 forni respectively the head and foot of the bed, and interlock with the outer bed frame sections l, 9 forming a rigid bedstead which cannot collapse Without having the locking means released by theattendant.
